Update Historic Windows for Charm and Efficiency
Renovate old windows to keep the character but lose the energy outflow from your home
What's better? To replace historic windows with new, low-emissivity windows and save energy? Or to keep the windows with their historic character and not save as much energy?
The debate rages between preservationists and designers-environmentalists, but there is a middle ground: renovating historic windows for the same performance as new windows. And there's a substantial argument for saving them.
Not only do they add character that makes a house unique, but old windows are generally thicker and last longer than today's windows, says the National Trust for Historic Preservation. Plus, as preservationists like to say, the greenest building (or window) is the one already built. No trips to the landfill. No new resources used.
Take a look at some of the ways that you can update your windows for energy efficiency, for a win-win situation.

Historic windows are often wholly unique, like this elaborate stained-glass entry in a historic Chicago home. It's unlikely to find similar windows in today's newly built houses.
If you're faced with leaky, old windows, Heritage BC, Canada's version of the National Trust for Historic Preservation, suggests starting by repairing the existing frame, sash and glass.
Windows can also be draftproofed and insulated with appropriate caulking and weatherstripping materials. For wood-frame windows, Natural Resources Canada suggests using a quality, self-adhesive plastic V-strip weatherstripping.

Adding indoor or outdoor storm windows and heavy drapes will help reduce the load on your heating and cooling systems.
The U.S. Department of Energy says that storm windows don't add to the insulating properties of single-pane windows, but they do reduce the movement of air in and out, thus reducing heating and cooling costs.

Adding extra locks to window sashes will help tighten a window's seal, preventing air inflow and outflow.
